java - 使用包含 CDATA 的 XML 配置 MOXy 的 @XmlPath

Question

我正在尝试使用 XPath 通过 EclipseLink JAXB (MOXy) 映射 XML 文档。但是当 XML 包含 CDATA 标记时会遇到问题示例:

<![CDATA[Jill's Box Company]]>

我正在使用 eclipselink-2.3.0 jar 来获取应用程序中的 XPath 映射。为了使 JAXB 使用此实现，我创建了一个 jaxb.properties 文件，其中包含以下内容:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

XPath 只能以这种方式工作，否则应用程序甚至不会获取注释 @XmlPath。

现在，在通过 unmarshaller 方法运行 XML 时，它会抛出空指针错误，如下所示:

更新

Hi Blaise, I updated the eclipse version to 2.4.1 and it solved the CDATA issue I was facing. Its all Good now.

我很高兴听到现在一切正常。下面是一篇有关 EclipseLink 2.4 中 MOXy 新增功能的文章:

由于您使用的是 EclipseLink 2.3.0，我相信您遇到了以下错误，该错误已在 EclipseLink 2.3.1 中修复。

EclipseLink 目前版本为 2.4.1，如果可以的话我建议升级到该版本:
